Equivalent Numerical Algorithm For The Strip-Rolling Process Of A Continuous Variable Crown Mill Using The Coupled Rigid-Plastic Finite Element Method, Tao Wang, Zhong-Kai Ren, Dong-Ping He

Journal of Marine Science and Technology

For the accurate simulation of the rolling process of a wide strip and plates, highly sophisticated algorithms must be developed to couple material flow behavior with the elastic deformation of rolls. A coupling simulation system based on a three-dimensional rigid-plastic finite element method (RPFEM), elastic-plastic finite element method, and influential function method was developed in this study. Calculation of the continuous variable crown (CVC) mill was more complex than that of the normal 4-high rolling mill. According to the point symmetry of the roll gap profile, the CVC curves of work rolls at various shifting positions were equal to various …
